Be it known that I, PETER GUsTAF LEON- a subject of the King of Sweden, and aresident of the city of Tulsa,

vented certain new and useful Improvements in Clutches, of which the'following is a specification. j

newv and useful the clutch spiderand reverse drum com-` bined in onemember, and has itsv forward and reverse drive mechanism mounted in sai-ddrum.r I f f vAnother object is to provide `a device which is safein operation, simple iii con-f struction, is easy to assemble or disassemble, and is highly eiiicientin use. y v Other objects will appear hereinafter. The invention consists in the combinations and arrangements of;y parts hereinafter de'-v scribed and claimed.

The invention will be l forming a pait of this specification', and in gages the drum; I l

-The form of construction illustrated com-v prises asupport l0l on the upper endof A .which is journalled one end of a shaft-1l,

and a cap 12`is placed over said shaft and fastened to said support. The other end of' saidshaft has an attachiiig-`member`13 rigidly mounted thereon, =ada`pted 'to be fas-5 the balance wheelof an engine (not 'A pulley is rotatably mounted shaft adjacent the attaching memtened to shown) on said bei' and'is provided with a sleeve 15 and a i of said sleeve.

1G beyondI the periphery A drum' V17 is` rotatably mounted on lsaid sleeve and is provided with cylindrical flange county of Tulsa, and State of Oklahoma, `haveinbest understood by reference to the accompanying drawings brake-band enare vertical sectional views longitudinal vertical sectionaly lugs 18'extending'laterally from-a radial web 19 of the drinn, which extend Within the cylindrical flange of the pulley. Pins 20 are mounted in the openingsin said lugs, each ofsaid pins carrying al shoe 21 on its outer end adapted to bear .on the'inte'rior of the cylindricaly flange, and `having a spring 22 mounted on the inner end, betweenv end of the bolt anda spring 3,1. seated beof;l said drum.

neathl said shoe andvin a Seaton the exterior I Af gear32'is fastened to the face of the I pulley Ysleeve l5, asby inean's'ofscrews 33,i

anda similar gear 34 lis keyedto the shaft. Pinions 35 are pivotally. mounted ony web 19in mesh with the pulley gear. and idleis are also .pivoted'to' -said web' in mesh with the shaft gear, each'idler meshingwith one ofsaid pinionsfv The lever 25 is connected'iat itsrouter I to a' pair of links 37 which have a pair of links 38 pivoted between' them, which' in turn .are pivoted to an arm 39 of a collar 40 kslidably mounted on the shaft 11. *,Aj

plurality of these arms, 'links and levers are provided, and a closing plate 41 seats/against the outerv rim of the drinn, formingahous-f ing therewith for the gears, and containsv slots -42 ini which the levers 25 operate. A

groove '43 is formed aroundsaid collarf'fina v which yoperate slices 44 attached tto a yoke y 45 yof-a lever 46', which is -pivoted at its middle :portion to'a bracket 47 fastened tov ico f the support v10, vand has aslot 48 at its lower end.`

An operating inember50 is pivotally con.

nected, by means of a pairof links 51 and a pin 452, to one corner of a triangular plate 53, which is pi-votally mounted on a pin 54 fastened on a curved bracketl 55 attached to'k the suppOrtlO. Threaded members 56' are pivoted to theother corners offsaidplate 53 and have their free ends fastened each to an end 57 of a brake band `58 engaging* around the drum 17. j vThedmemlier- 50 is provided with a side lug 59' to which is piv-V oted one arm 60 of a bell crank pivoted at 61 to the bracket 55, the other arm 62 of the bell crank engaging in the slot 48. A disc 63 is mounted lon said shaft, adjacent the closing plate 41.

In operation the member 50 is thrust forward ltoward the device which carries the arm 60 of the bell crank forward and moves the free end of the crank arm 62 towards the right, as viewed in Fig. 3, carrying with it the lower partof the lever thereby forc ing the sleeve and the toggle inward toward the clutch. This action brings the connected ends of the links 37 andthe associated links 38 against the disc 63, the links 3S slanting inward towards said disc. The

' further inward moif'ement of the collar a() straightens out these links 38 forcing them in a direction radial to the shaft, there-by drawing the links 37 and the outer ends of the levers 35 inwards towards the shaft. 'lheheads 27 of the bolts 26 will act as fulcrums foi the levers' forcing the bolts in ward and with them the shoes 29 into contact with the flange 16 of the drum', at the same time the inne-r ends of the levers will force the shoes 21 outwards toward the inside of said flange 16. During said movement of the clutch operating mechanism plate 53 hasl been partly rotated upon the pin 54, thereby separating the ends 57 of the band 58 and loosening said band upon the drum 17, as shown in Fig. 5. 7With the members in this position, the clutch spider of the drum engages the flange of the pulley and the drum and pulley rotate together.

` The gears and pinions mounted on the shaft,

pulley and drum will lock the shaft with the pulley and force the sha-ft to also rotate in unison with the drum and pulley, that is, all members rotate in a forward direction. l/Vhen the operating member 50 is drawn outwards the collar 40 drawn away from the drum and toward the support and the clutch members are released from the flange of the pulley. At the saine time the plate 53 is partly rotated upon the pin 5ft bringing the ends 537 of the brake-band 58 together and thereby tightening' said band upon the drum to hold the drum against ro tation. The rotation of the pulley will now carry with it its attached gear 32 which will rotate the pinions 35 and through them the idlers 36 meshing with the gear 34 keyed to the shaft. The arrangement of these gears, pinions and idlers will rotate the shaft in a direction reverse to that of the pulley.

It is thus evident that by an inward thrust of the operating member 50 the clutch members become operative and the brakeband is released, and the pulley, drum, shaft and associated members rotate in unison; and that by an outward thrust of the operating member 50' the clutch members are released and the brake-band engages the drum and holds the same, where upon the pulley and shaftrotate in reverse directions.

Vhile I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise detai-ls of the construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
